IMPROVEMENT -IN PAPER-RULING MACHINES.

Specification forming part of Letters Patent No. 157,629, dated December 8, 1874; application filed October 30, 1874.

To all whom it may concern:

Be it known that I, DANIEL MoRTnvrER, of the city of Ottawa, in the county of Carleton, in the Province of Ontario, Canada, have invented certain new and useful Improvements in the Art of Ruling Paper; and I do hereby declare that the following is a full, clear, and exact description of the same.

The object ot' this invention is to facilitate the ruling of special lines, which stop at right angles to other lines, or without crossing the same; and it consists in the employment of pattern-sheets of paperlaid upon the sheets to be ruled, and in which patternsheets are cut or punched openingsto allow the pens of a ruling-machine to strike upon the underlying sheet to be ruled, the pattern-sheet receiving the continuation of the lines from stop7 to strike Figure l is a diagram of complete pattern to be ruled. Fig. 2is a diagram of the punctured pattern-sheet employed in ruling some of the strike and stop lines, terminating at right angles to other lines, and showing the continuation lines thereon from stop to strike. Fig. 3 is a diagram showing strike to stop` lines on the p. per to be ruled, as made from pattern, Fig. 2.

Special lines, such as will be referred to in this specification, are now ruled by intermittently dropping and lifting the pens, which requires great careto strike and stop at the moment the portion of the sheet to be ruled is passing under the pens. This is a very tedious `and slow method, and requires a trained o'perator to do intricate work, and in many cases the sheets to be ruled have to be passed several times through the machine to rule parallel lines, but terminating at points not in a direct line with each other. y

By my mode of ruling these special lines no intermittent lifting ot' the pens is required, and hence no highly-skilled labor or care is required in performing the work, and the sheets can be ruled with the rapidity of ordinary rul- 1n g.-

In ruling a sheet, Figs. 1 and 3, the through lines A are first ruled. I then take a sheet ot' paper, B, Fig. 2, of the same size, and out therein openings O, of the length of the lines to be ruled, and in such places Where they are to commence and end on the sheet to be ruled. I then lay the pattern-sheet B on the sheet, Figs. 1 and 3, and pass them together through the ruling-machine. The consequence will be that the pens will rule the lines b ot' Fig. 2 on the pattern-sheet, and the lines d on the sheet, Fig. 3, to be ruled, the lines on the sheet, Fig. 3, striking and stopping on ther said sheet through the opening O of the pattern-sheet. The other lines, c f g, Fig. l, transversely thereto, may then be ruled bythe employment of another patternsheet, in which are cut openings which correspond to the length and distance apart of the said lines e, which patternsheet is laid on the sheet, Fig. l, to be ruled, and passed through the ruling-machine to receive the ink from the pens, as previously described.

When ruling lines which are to terminate at the intersection of a through line, and run from the opposite edge of the sheet to be ruled, I

employ a strip of paper folded over the edge to the desired width to receive the continuution of the lines, as described for the patternsheet.

I claim as my invention- A pattern-sheet, Fig. 2, laid upon the sheet to be 'ruled when passing' through the rulin machine, having openings c to allow'the pelis of the ruling-machine to strike upon the underlying' sheet to be ruled, the pattern-sheet receiving' the continuation of the lines from stop to strike, substantially in the manner and for the purpose set forth.

DANIEL MORTIMER.
